UNITED STATES HENRY S. BOSTON, OF CALLAWAY, NEBRASKA.

GULTIVATOR Application filed January This invention is an attachment for tworow l ster cultivators and has for its object the provision of simple means whereby the shields may be easily adjusted without re- 5 quiring the driver to leave his seat. The invention is illustrated in the accompanying drawings and will be hereinafter fully set forth.

In the drawings:

Figure 1 is a plan view of a two-row lister cultivator having my invention embodied therein;

Fig. 2 is a side elevation of the same, and

Fig. 3 is a rear elevation thereof.

The cultivator comprises a cross bar or beam 1 to which is secured a seat standard 2 carrying a seat 3 all of the usual or approved form. To the ends of the cross beam 1 are secured the cultivator frames 4 from which cultivator beams 5 extend rearwardly.

These parts may be of any construction now generally employed in lister cultivators and are illustrated as carrying cultivator disks 6 and 7 upon the frame 1 and adjacent the front ends of the beams 5, while cultivator shovels 8 are carried by the rear ends of the beams.

In carrying out my invention, 1 secure upon the cultivator beams 5 the standards or brackets 9, at the upper ends of which are mounted, as at 10, rock shafts 11 which are equipped between their ends with cranks 12. The shields 13 are of the usual arched or inverted V-shape formation and are adapted to run along the rows of plants so as to cover the young tender shoot-s and prevent them being buried under the dirt turned over by the cultivator disks and shovels. Chains 14 or similar flexible connections are secured to and extend between the rear end of each shield and the crank 12 of the rock shaft 11 immediately above said shield, :while the front ends of the shields are supported by hangers 15 which have their rear ends engaged in the front end portions of the respective shields at opposite sides of the central longitudinal line thereof while the front ends of the hangers are loosely mounted upon the cross beam 1, as shown at 16. These hangers normally extend downwardly and rearwardly from the cross beam and ma rock relative to the cross beam and the shield ATTACHMENT.

so as to accommodate the vertical movement of the latter. Each rock shaft .11 is held firmly to its supporting standards 9 so that it will have frictional engagement therewith sufficient to hold it in any position to which it may be adjusted.

The cultivator is drawn over the field in the usual manner and, if the shields are to be used, the hand levers 17 are swung rearwardly so as to assume a vertical position, as shown at the right in Figs. 1 and 3, it being noted that the crank 12 of each rock shaft 11 is disposed approximately in alinement with the lever on said shaft so that, when the lever is turned up to a vertical vposition,the crank will swing downwardly and will thereby permit the shield to be lowered, as shown most clearly by full lines at the right in Fig. 3, whereas, if the lever be swung forwardly, as shown clearly in Fig. 2, i

the crank will be swung upwardly and the shield will be raised as represented by the dotted lines in Fig. 3. It will be understood that by thus setting the respective levers in the proper position the shields may be easily raised or lowered to any desired eX- tent and, therefore, will entirely cover the plants or will partly expose them so that fine surface soil may be thrown close around the plants under the side edges of the shields. It will also be understood that the shields may be adjusted independently, as clearly shown by Fig. 3, and may thus be set as may be deemed most desirable under any given conditions. My attachment is exceedingly simple in the construction and arrangement of its parts and may be readily applied to any cultivator now in use. When the at tachment is applied, the operator may easily adjust the shields without leaving his seat and may vary the adjustment from time to time as may be necessary without stopping the progress of the cultivator or interfering with the work being done.

Having thus described the invention, I claim:

In a lister cultivator including a cross bar, a transverse member connected to the cross bar, cultivator beams pivoted to the transverse member, standards at the rear ends of the cultivator beams, a transverse shaft forming connecting means between the rear ends of the cultivator beams and friotionally mounted in the standards to maintain the beams in an adjusted position and having an intermediate crank portion, an operating 5 lever associated With the shaft, a shield between the cultivator beams, hangers inclined rearwardly and downwardly and loosely mounted on the cross bar and engaging the front end of the shield, and connecting means between the rear end of the shield and the crank portion of the transverse shaft.

In testimony whereof I aflix my signature.
